PyLR -- Fast LR parsing in python What is PyLR? PyLR stands for Python-LR, where the LR is as in LR parsing. It is a parser generator for python (1.5b1 or better). Included is an extension module implementing the LR parsing algorithm an 'engine' builtin type, a parser generator script, and class interfaces to Lexers and LALR(1) Grammars, html documentation, and example code (PyLR uses its own interface to parser context free grammars). author/contact: scott@chronis.icgroup.com
